Hi
I have some views that are UNIONS of two identical (asside from name)
tables. I have noticed that some of these views have stopped
functioning. Running a select on them returns no results (TIBOQuery) if
I browse the data (from IB_UtilitiyBar) selecting the view displays a
string or numeric overflow error.
Running a select on the view in FlameRobin correctly returns results.
Running the views source query in IBOQuery works fine to.
I suspect it is something to do with the logic used to determine the
resulting field sizes from a view not correctly handling UTF8. It is
data sensitive and I guess it only fails where stored data nears the
field limit. The views work on some of my datasets :)
I'm off home for the weekend soon so won't be able to reply for a while.
Cheers
Rob
